DEBKAfile recently leaked the background information behind the currently ongoing preparations for an Israeli attack on Iranian nuclear weapon facilities.

Iran has completed the development of a nuclear weapon and awaits nothing more than a sign from Supreme Leader Ayatollah Ali Khamenei to start assembling its first nuclear bomb, said Israeli Military Intelligence Chief Major General Aviv Kochavi on Thursday, February 2. Assembling a bomb would take up to a year, Kochavi estimated. With 100 kilograms of uranium enriched to 20 percent grade and another 4 tons of uranium enriched to 3.5 percent already in stock, Iran would need another two years to make four nuclear bombs.

Therefore, by the end of 2012 or early 2013 Iran may have a single nuclear bomb, but by 2015 the figure would jump to four or five.

The officer was essentially amplifying the words of his predecessor, Maj. Gen. (res.) Amos Yadlin, who said on Jan. 26 that as long ago as 2007 or 2008, Iran had already passed the point of no return in developing nuclear weapons. Kochavi agreed with him that none of the sanctions imposed thus far had persuaded Iran to slow down, least of all shut down, its drive for a nuclear weapon.

His comments coincided with the findings published Thursday by the Enterprise Institute, an American think tank, that Iran would be able to manufacture a 15-kiloton nuclear bomb as soon as August of this year, just seven months from now.

Also Thursday, Deputy Prime Minister Moshe Yaalon disclosed that the big blast at the Iranian missile base near Tehran last November blew up a new missile system with a range of 10,000 kilometers, capable of targeting the United States.

The single biggest danger in the Middle East today is not the risk of a six-day Israeli war against Iran. It is the risk that Western wishful nonthinking allows the mullahs of Tehran to get their hands on nuclear weapons. Because I am in no doubt that they would take full advantage of such a lethal lever. We would have acquiesced in the creation of an empire of extortion.

War is an evil. But sometimes a preventive war can be a lesser evil than a policy of appeasement. The people who don’t yet know that are the ones still in denial about what a nuclear-armed Iran would end up costing us all.
